Create SharePoint Group from Active Directory Group:

If you have an existing Active Directory group, You may want to convert it to a SharePoint Group to remove the dependency on AD Administrator.

#Import Active directory & SharePoint PowerShell modules
Import-Module ActiveDirectory
Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue
#Variables for processing
$ADGroupName="SP13 Authors"
$SPGroupName="Content Authors"
$PermissionLevel="Full Control" #Permission to SPGroup
$Domain="Crescent" #AD Domain

#Get the Site collection's Root Web
$web = Get-SPWeb $SiteURL

#Check if Group Exists already
 if ($web.SiteGroups[$SPGroupName] -ne $null)  
  write-Host "Group Name Already in the site!!" -ForegroundColor Red 
  #Create New SharePoint Group
  $SPGroup = $web.SiteGroups.Add($SPGroupName, $web.Site.Owner, $web.Site.Owner, $null)
  #Get the newly created group and assign permission to it
  $SPGroup = $web.SiteGroups[$SPGroupName]  
  $RoleAssignment = new-object Microsoft.SharePoint.SPRoleAssignment($SPGroup)  
  $RoleDefinition = $web.RoleDefinitions[$PermissionLevel]  
  Write-Host "New Group $SPGroupName has been created!" 
  #Get Members of AD Group
  $ADGroupMembers = Get-ADGroupMember -Identity $ADGroupName | Select-Object -ExpandProperty SamAccountName    
  Write-host "Total Users Found in the AD Group:"$ADGroupMembers.Count

  #Add Members to SPGroup from ADGroup
  $ADGroupMembers | ForEach-Object {
     #Convert to Domain\User format
     $UserID =  "$Domain\$_" 
     #Get Claims ID. E.g. Domain\User to i:0#.w|Domain\User
     $UserClaimsID = (New-SPClaimsPrincipal -identity $UserID -IdentityType "WindowsSamAccountName").ToEncodedString() 
     $SPGroup.Users.Add($UserClaimsID,"", "", "") 
     Write-host "User Added from AD Group to SharePoint Group:" $UserClaimsID

Active Directory PowerShell Module:
You need to have an “Active Directory module for Windows PowerShell” in Windows Server 2008/2012 member servers. Use this PowerShell cmdlet to add this feature:

Add-WindowsFeature RSAT-AD-PowerShell 

Alternatively, you can Go to: Server Manager >> Add Roles and Features >> Choose “Active Directory Module for Windows PowerShell” under Remote Server Administration Tools.
